[Django]-How do I add a "class" to a ChoiceField in Django?

I had a quick read of https://docs.djangoproject.com/en/1.4/ref/forms/widgets/

which rabbited on about widgets – apparently they are

Django’s representation of a HTML input element. The widget handles the rendering of the HTML

and then each form field is tied to a widget – have a read of:

https://docs.djangoproject.com/en/1.4/ref/forms/fields/#built-in-fields

for the ChoiceField, the defaultWidget is “Select” (as noted in the above link). Ok, knowing the right widget, to add the class i just needed:

widget=forms.Select(attrs={'class':'regDropDown'})

so that my final line ended up reading:

gender = ChoiceField(label='', choices=SEX, widget=forms.Select(attrs={'class':'regDropDown'}))

Huzzah!
